Review on 🔥 Dorman M390259: High-Performance New Brake Master Cylinder for Superior Braking by Jeremy Gums

Purchased in October 2018 for my 1998 GMC K2500 with 286,000 miles on it. Yesterday 12/30/20 on the way home from work the brakes fell on the floor. I have driven this truck 306,500 miles so far. Mostly interstate miles. I don't pull a trailer. I have installed 5 or 6 master cylinders on my Ford and GM vehicles for the last 25 years. None of the others failed so easily. I have never used Motorcraft or ACDelco. But now the quality of goods from abroad seems to be lacking. I bought the Wearever brand today to get back on the road but I will be replacing ACDelco soon.
